China and India are not friends. China needs Myanmar because it would allow it to transfer its goods faster and cheaper: no need to go around through Strait of Malacca.

If pro-China government is installed in Myanmar it means that it automatically becomes hostile to India.

Controlling trade routes explains many wars and coups.

To be honest I know next to nothing about Myanmar<->India relations. Everyone has been suggesting that the new Myanmar government is closely related to China, so I was substituting in the China<->India relations.

Right now yes. However any neighboring country with a recent coup doesn't fill you with confidence.
